Sh bad substition error
If you see the following error when building a dockerfile:
sh: 1: Bad substitution
It's likely caused by your dockerfile running sh and not bash which doesn't support variables with v. such as the version of AWS OFI NCCL:

The solution is to set the shell in your Dockerfile:
SHELL ["/bin/bash", "-c"]
